Cardinals vs Marlins Prediction
The Marlins are 5-3 in their last 8 meetings against the Cardinals but both teams are tied 3-3 in their last six meetings in Miami.
In this Cardinals vs Marlins Prediction, the Marlins are coming as -135 home favorites. Both teams are coming into this matchup in opposite trajectories, as the Cardinals have five consecutive wins and are coming off a series sweep against the Astros where they scored 23 runs in three games. On the flip side, the Marlins are 2-7 in their last 9 games and have 6+ earned runs in five of their last eight games. McGreevy has been looking great for the Cardinals so far, so I like the value with the road dog in this spot. Take the Cardinals on the moneyline for plus money.
